Yes it absolutely is and will be used as such, this is EXACTLY how google play remote attestation works and a necessary building block for doing it in the browser. It is the exact reason why microsoft and google are pushing for tpms in windows 11 and it's already a reality on android and every grapheneos user knows the pain[0] and is the absolutely logical next step.
I read that not as a claim that this is an attestation mechanism, but that this is another step towards that. Given that Google has previously discussed implementing the Web Integrity API, it's not so large a leap as to be dismissed as disconnected from reality.
